SPECIFICATION formingpart of Letters Patent No. 699,499, dated May 6, 1902.

' Application filed December 31,1901 filerial No. 87,915. (No model.)

To aZZ whom it may concern.-

Be it known that I, ROBERT B. DIOKIE, a

citizen of the United States, residing at Kenosha, in the county of Kenosha and State of Wisconsin, have invented certain new and useful Improvements in Fountain-Pens; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to fountain-pens of the stylographic type.

The object of the invention is to provide a fountain-pen of this character which shall be simple of construction, durable in use, comparatively inexpensive of production, and which may be easily and quickly filled or charged with ink,and which when in inverted position in the pocket will prevent leakage of ink therefrom.

With this and other objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts, which will be hereinafter more fully described, and particularly pointed out in the appended claim.

In the accompanying drawings, Figure l is a perspective view of my improved stylographic pen, and Fig. 2 is a longitudinal vertical sectional view.

The pen embodies in its construction an inkholdingbarrel 1,-havinga pointed end 2,formed with a minute outlet channel or opening 3 and provided at its opposite end with a capillary tube 4, which projects within the barrel and leaves an intervening space or chamber 5 between it and the inner wall of the barrel. The tube is open at each end.

To fill the barrel, the point is inserted into the ink and suction applied to the opposite end of the barrel, thus creatinga vacuum, which is filled by the inflowing ink. The inflowing ink, owing to the employment of a capillary tube, will not be drawn out through the open end of said tube nor will it escape when the pen is inverted-the position it occupies when in the pocket. To prevent the too rapid feed of the ink through the chan= nel or duct 3, I provide the barrel at aplace in its length where it merges into the point 2 witha packing of hygroscopic material, such as absorbent cotton, which While permitting of the filling of the barrel by the formation of a vacuum therein will also tend to retard the flow of ink through the channelin the point, and thus regulate or control the flow.

From the foregoing description, taken in connection with the accompanying drawings, the construction, mode of operation, and advantages of the invention will be readily understood without requiring an extended eX- planation. It may be well to note that the pen consists of but a single piece of material, preferably transparent, and may be of glass, and that there are no valves or movable parts to become clogged or injured by the action of theacid in the Writing fluid.

Various changes in the form, proportions, and details of construction may be made within the scope of the invention without departing from the spirit or sacrificing any of the advantages thereof.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

In a stylographic pen, the combination of a transparent barrel terminating in a point formed with an ink duct or channel,- said batrel having formed integrally with its opposite end an inwardly-projecting capillary tube open at each end and spaced from the barrel to form a chamber whereby is produced a capillary attraction which prevents the escape of writing fluid when the pen is in an in-.

verted position, substantially as set forth.

In testimony whereof I have hereunto set my hand in presence of two'subscribing Witnesses.
